Why I chose gatsby-source-prismic
This note provides extra context on the tutorial Create a Prismic powered Gatsby site from scratch.
At the time of my writing (Wednesday, June 10th 2020), there are two Gatsby plugins for sourcing your Prismic data.
I chose to use gatsby-source-prismic.
There are pros and cons to each of these source plugins. (This issue)[https://github.com/angeloashmore/gatsby-source-prismic/issues/217] and the comments within give a great overview of the current state of things.
I chose gatsby-source-prismic because it is lightweight (creating pages are not a feature of this plugin) and appears to have a better developer experience (I formed this opinion based on some light reading through each repo's issues). I anticiapte these plugins changing and will revisit this decision in the future.
